Dermatoglyphics in the Bushmen

Analysis of the dermatoglyphics of a sample of Kung Bushmen living in the Kalahari of north-east Namibia is presented, and the results are compared with those of other Bushmen studies. A high frequency of arches, a low ridge count, and high frequencies of pattern reduction forms, appear characteristic.     

Dermatoglyphics in Phenylketonuria

The dermatoglyphic characteristics on the fingertips, palms and soles of 100 Polish children with proven diagnosis (urine test and blood serum tests) of PKU and of the parents of 23 of them were studied. Our results confirm that PKU is not characterized by dermatoglyphic differences. An apparent diminution in complexity of finger pattern type in patients is shown to be due to the genetic relationship between the parents and their offspring rather than the influence of the PKU disorder itself.

Dermatoglyphics in pathology with emphasis on breast cancer and cervix carcinoma: Some results

The finger and palmar prints of 118 women with breast cancer and of 37 women with cervix carcinamo were studied. The results were compared with two groups of healthy women, the first consisted of aged women (average age of 78.94) and the second of young women. Only four differences out of ten (40%) were significant between women with breast cancer and young women. One difference out of ten (10%) was significant in the comparison between women with carcinoma of the cervix and elderly women and two (20%) in the comparison to young women. In general, compared with the healthy women the sick women present an increase in whorls and a decrease in a-b ridge count. The results obtained seem to demonstrate that dermatoglyphics are not a good diagnostic tool in the study of these two types of cancer.     

The Chipaya of Bolivia: Dermatoglyphics and ethnic relationships

Dermatoglyphic data on 15 traits (digital arches, digital radial loops, digital ulnar loops, digital whorls, I loops, I_r loops, H loops, ? loops, III loops, IV loops, mainline C absence, total ridge count, a-b ridge count, atd angle, and mainline index) are presented for 141 Chipaya Indians of Bolivia. Ethnic relationships of these Indians to nine South American Indian tribes (Alacaluf, Atacameño, Aymara, Cashinahua, Chácobo, Chama, Chané, Quechua, and Sirionó) are explored by means of a genetic distance analysis using 21 alleles. Genetic distances are complemented with linguistic and geographic distances between the Chipaya and the other tribes. Genetic distances were found not to be significantly correlated with linguistic and geographic distances. Combining the information available, it is concluded that the Chipaya are most likely ethnically related to the Arawak speakers of the tropical forest.     

Absence of triradius d in a three-generation pedigree and other variations of main-line D

An example is reported of a rare dermatoglyphic variant (absence of triradius d) in a woman of mixed European and Cherokee American Indian ancestry. This variant was not present in her parents, her five siblings, four nephews or one niece. Attention is drawn to the continuum from an absent triradius d to a triradius with an abbreviated main-line associated with either an open field in interdigital area IV, or a loop in interdigital area IV or a tented arch at d. This same continuum occurs at c. The absent triradius at d is extremely rare and the tented arch at d is very rare.     

Dermatoglyphics of the nganasans and the forest entsy from the Taimir Peninsula

Dermatoglyphic data on 17 traits (digital arches, ulnar loops, whorls, patterns on the hypothenar and thenar/I,II,III, and IV interdigital areas, main line C absence and its incompleteness, mean digital ridge-count, a–b, b–c, and c–d ridge–counts, atd angle, pattern intensity index, and main line index) are presented in this paper for 194 males and 224 females from the Taimir Peninsula. Also presented is a population analysis of the Taimir aborigines based on quantitative traits, and comparisons of this population with some Siberian and North American populations.     

Dermatoglyphics of Easter Islanders analyzed by pattern type,admixture effect,and ridge count variation

The adult Easter Island population was fingerprinted in 1965 as part of an overall study of their human biology. Major findings of the dermatoglyphic analysis are as follows. Digit and bimanuar percentages of patterns (arches, loops, and whorls) were similar to those observed in Europeans. However, in terms of total pattern type distributions, the Islanders had many more whorls and a correspondingly much higher Pattern Intensity Index than those found in European groups. This difference was even present, although in lesser magnitude, in Easter Islanders known to be admixed with Europeans. Corresponding to a high occurrence of whorls, Mean Total Ridge Count (TRC) was also notably high. An association between TRC as a measure of pattern size and incidence of patterns was clearly evident in several groups available for comparison.     

Digital dermatoglyphic patterns in a sample of the Nigerian population

Eight hundred Nigerians (400 males and 400 females) were screened for the analysis of digital dermatoglyphic patterns. The frequency distribution of the patterns are 52.09%, 27.67%, 19.20% and 1.13% for ulnar loops, whorls, arches and radial loops respectively. Except for arches, the males have more of the patterns than females. The pattern intensity indices for males and females are 11.2 and 9.9 respectively. Bilateral symmetry is similar in both sexes and the percent distribution is as high as 81.5% and 84% on digit V in males and females respectively.     

The effect of a pattern in palmar interdigital II on a-b ridge count in black and white Down syndrome cases and controls

An unconfirmed study by Fang (Ph.D. thesis, Univ. of London, 1950) in Britain showed that individuals with Down syndrome had lower total a-b ridge counts in palmar Interdigital area II (ID II) than a group of controls. This study compares 603 white Down syndrome cases and 93 black Down syndrome cases with 668 white and 402 black controls. Our results confirm those of Fang in that the Down syndrome cases in both racial groups had lower total a-b ridge counts than their respective controls. In addition, the black controls and Down syndrome cases had lower a-b ridge counts than their white counterparts. The mean a-b ridge count was significantly lower in individuals with a pattern in ID II compared to individuals without a pattern in ID II in both the Down syndrome and control groups. Some of the lower a-b ridge counts in the Down syndrome samples can be accounted for by the fact that there is an increased frequency of a pattern in ID II in Down syndrome cases. Both Down syndrome and normal individuals who had a pattern unilaterally had a lower than expected a-b ridge count on the contralateral hand that did not have a pattern. There was a tendency also for increased asymmetry in Down syndrome cases with a pattern in ID II.

Studies of endemic cretinism in Papua New Guinea: digital and palmar dermatoglyphic patterns

We have tested the hypothesis that the abnormal development of the central nervous system seen in endemic cretinism might be accompanied by concurrent abnormal dermatoglyphic patterns. We compared digital and palmar dermatoglyphics of normal individuals and endemic cretins inhabiting the Huon Peninsula of Papua New Guinea. The population sampled from the Irumu River Valley included 118 males and 114 females with 22 male cretins and 23 female cretins. The population sampled from the Wantoat River Valley included 72 males and 38 females with 12 male cretins. No pathognomonic patterns were found that could identify the endemic cretin subpopulation. However, the occurrence of a number of differences between controls and cretins suggests that subtle changes in dermatoglyphic patterns accompany the anomalous development of the CNS secondary to maternal iodine deficiency. We discuss the significance of these findings and compare the dermatoglyphic patterns of normal Irumu and Wantoat natives and 21 other populations of Papua New Guinea.

Dermatoglyphics of schizophrenics, patients with Down's syndrome and mentally retarded males as compared with Australian Europeans using multivariate statistics.

Dermatoglyphics of schizophrenics, patients with Down's syndrome and mentally retarded males were compared with those of normal Australian Europeans. A computer programme of multivariate analysis of fifteen dermatoglyphic features was utilized. This analysis produces two significant variates of each of the populations plotted in two-dimensional space. The distance, measured in arbitrary units, between any two populations was studied for its significance. It was noticed that the patients with Down's syndrome separated significantly from the rest of the groups. The importance of multivariate analysis in the study of dermatoglyphics in comparing two or more populations is discussed.
